TC1321 10-Bit Digital-to-Analog Converter with Two-Wire Interface Features General Description • • • • The TC1321 is a serially accessible, 10-bit voltage output, digital-to-analog converter (DAC). The DAC produces an output voltage that ranges from ground to an externally supplied reference voltage. It operates from a single power supply that can range from 2.7V to 5.5V, making it ideal for a wide range of applications. Built into the part is a Power-on Reset (POR) function that ensures that the device starts at a known condition. 10-Bit Digital-to-Analog Converter 2.7-5.5V Single Supply Operation Simple SMBus/I2CTM Serial Interface Low Power Operation - Normal Mode: 350 µA - Shutdown Mode: 0.5 µA • Temperature Range: 40°C to +85°C • 8-Pin SOIC and 8-Pin MSOP Packages Communication with the TC1321 is accomplished via a simple 2-wire SMBus/I2C compatible serial port, with the TC1321 acting as a slave only device. The host can enable the SHDN bit in the CONFIG register to activate the Low Power Standby mode.

TC1321 3.0 DETAILED DESCRIPTION 3.2 Output Amplifier The TC1321 is a monolithic 10-bit digital-to-analog converter that is designed to operate from a single supply that can range from 2.7V to 5.5V. The DAC consists of a data register (DATA), a configuration register (CONF), and a current output amplifier. The TC1321 uses an external reference which also determines the maximum output voltage. The TC1321 DAC output is buffered with an internal unity gain rail-to-rail input/output amplifier with a typical slew rate of 0.8V/µs. Maximum full scale transition settling time is 10 µsec to within ±1/2LSB when loaded with 1 k in parallel with 100 pF. The TC1321 uses a current steering DAC based on an array of matched current sources. This current, along with a precision resistor, converts the contents of the DATA Register and VREF into an output voltage, VOUT, that is given by: The TC1321 allows the host to put it into a Low Power (IDD = 0.5 µA, typically) Standby mode. DATA V OUT = VREF ---------------1024 3.1 3.3 In this mode, the D/A conversion is halted. The SMBus port operates normally. Standby mode is enabled by setting the SHDN bit in the CONFIG register. Table 3-1 summarizes this operation. TABLE 3-1: Reference Input The reference pin, VREF, is a buffered high-impedance input. Because of this, the load regulation of the reference source needs only to be able to tolerate leakage levels of current (less than 1 µA). VREF accepts a voltage range from 0 to (VDD – 1.2V). Input capacitance is typically 10 pF. 2010 Microchip Technology Inc. Standby Mode 3.4 STANDBY MODE OPERATION SHDN Bit Operating Mode 0 Normal 1 Standby SMBus Slave Address The TC1321 is internally programmed to have a default SMBus address value of 1001 000b. Seven other addresses are available by custom order (contact Microchip Worldwide Sales and Service). See Figure 3-1 for the location of address bits in SMBus protocol.

FIGURE 3-1: DS21387C-page 8 SMBus/I2C Protocols. 2010 Microchip Technology Inc. TC1321 4.0 SERIAL PORT OPERATION 4.1 START Condition (START) The Serial Clock input (SCL) and bi-directional data port (SDA) form a 2-wire bi-directional serial port for programming and interrogating the TC1321. The following conventions are used in this bus architecture. The TC1321 continuously monitors the SDA and SCL lines for a START condition (a HIGH to LOW transition of SDA while SCL is HIGH), and will not respond until this condition is met. TABLE 4-1: 4.2 Term TC1321 SERIAL BUS CONVENTIONS Explanation Transmitter The device sending data to the bus. Receiver The device receiving data from the bus. Master The device that controls the bus: initiating transfers (START), generating the clock, and terminating transfers (STOP) Slave The device addressed by the master. START A unique condition signaling the beginning of a transfer, indicated by SDA falling (High Low) while SCL is high. STOP A unique condition signaling the end of a transfer, indicated by SDA rising (Low - High) while SCL is high. Address Byte Immediately following the START condition, the host must transmit the address byte to the TC1321. The 7-bit SMBus address for the TC1321 is 1001000. The 7-bit address transmitted in the serial bit stream must match for the TC1321 to respond with an Acknowledge (indicating the TC1321 is on the bus and ready to accept data). The eighth bit in the Address Byte is a Read-Write bit. This bit is a 1 for a read operation or 0 for a write operation. During the first phase of any transfer, this bit will be set = 0 to indicate that the command byte is being written. 4.3 Acknowledge (ACK) ACK A receiver acknowledges the receipt of each byte with this unique condition. The receiver drives SDA low during SCL, high of the ACK clock pulse.The master provides the clock pulse for the ACK cycle. Acknowledge (ACK) provides a positive handshake between the host and the TC1321. The host releases SDA after transmitting eight bits, then generates a ninth clock cycle to allow the TC1321 to pull the SDA line LOW to Acknowledge that it successfully received the previous eight bits of data or address. Busy Communication is not possible because the bus is in use. 4.4 Not Busy When the bus is IDLE, both SDA and SCL will remain high. Data Valid The state of SDA must remain stable during the High period of SCL in order for a data bit to be considered valid. SDA only changes state while SCL is low during normal data transfers. See START and STOP conditions. All transfers take place under control of a host, usually a CPU or microcontroller, acting as the master, which provides the clock signal for all transfers. The TC1321 always operates as a slave. The serial protocol is illustrated in Figure 4-1. All data transfers have two phases; all bytes are transferred MSB first. Accesses are initiated by a START condition (START), followed by a device-address byte and one or more data bytes. The device-address byte includes a Read/Write selection bit. Each access must be terminated by a STOP Condition (STOP). A convention called Acknowledge (ACK) confirms receipt of each byte. Note that SDA can change only during periods when SCL is LOW (SDA changes while SCL is HIGH are reserved for START and STOP conditions). 2010 Microchip Technology Inc. Data Byte After a successful ACK of the address byte, the host must transmit the data byte to be written or clock out the data to be read. (See the appropriate timing diagrams.) ACK will be generated after a successful write of a data byte into the TC1321. 4.5 Stop Condition (STOP) Communications must be terminated by a STOP condition (a LOW to HIGH transition of SDA while SCL is HIGH). The STOP condition must be communicated by the transmitter to the TC1321. Refer to Figure 4-1, for serial bus timing.
